CASH REGISTER AND INDICATOR.

SPECIFICATION forming part of Letters Patent No. 444,391, dated January 6, 1891.

Application tiled August l1, 18 90.

To all whom, may concern:

De it known that I, IVILLIAH H. CLARK, a citizen oi the United States, residing at. Albion, in the county of Erie and State of Pennsylvania, have invented certain new and usc- Inl Improvements in Cash Indicators and Registers 5 and I dolierehydcelare the following to he a full, clear, and exact description of the invention, such as will enable others skilled inthe art to which it appertains to make and use the same, reference being had to the accompanyingdrawings, and tothe letters and figures of reference marked thereon, forming part ot' this specilieation.

My invention consist-s in the improvements in cash indicators and registers hereinafter' set forth and explained,and illustrated in the accompanying drawings, in which Figure l is a perspective view ol' my improved eash indicator and register, one of the side frames being left ot'f and other parts broken away. Fig. i is a top or plan view o'll my improved cash indicator and register. Fig. 3 is a front view of same, partlyin elevation and partly in section, on the line ai' in Fig. 2, looking in the direction of the arrow. Fig. a is a detail view of a portion of the same. Fig. 5 is a transverse section of same on the line y y/ in Fig. 2, looltingin the direction of the arrow. Fig. (5 is a detail view of the compound key-lever mechanism of my machine. Fig. T is a rear view ot' the same in elevation. Figs. 8 and il are detail views ol. portions of the same.

YLike letters and figures refer to like parts in all the views.

In the construction shown of my improved cash indicator and register the frame consists oi the sides A A, connected bya plate B,whieh rests upon and is secured to a hase I3', in which the cash-drawer of the machine operates.

On arod A' in the lower part ot the sides A A of the frame are pivoted four groups of key-levers O, O', O3, and O3, the group O representing cents from one to nineinclusive, the group C' multiples of cents from ten to ninety` inclusive, the group C? dollars from one to nine, inclusive, and the group O3 multiples of dollars from ten to ninety, inclusive.

Serial No. 361,750. (No model.)

In the vertical grooves I) I) l) b in the face of the frame-plate B y are vertically-sliding rack-bars D D' D`2 D'n, on which are feet d, d', (Il, and di", the vIfeet d resting upon and being actuated hy the group of key-levers C, the foot d resting upon and heing actuated by the group ol' I ey-levers C', the toot (I2 resting upon and being actuated by the group of lteylevers C2, and the foot d resting upon and being actuated hy the group of key-levers O3, each of said groups being adapted to operate the foot resting thereon and the rack-oar secured to such feet only.

To the i'acl;bais D, D', D?, and Ds are secured racks a, d', d'2, and d and c, c', c2, and c3, the racks d d' a? di respectively intermeshing with and actuating pinions e., e', e?, and e, secured to indicator-wheels E, E', E2, and D",

respectively, said pinions and indicatorwheels being mounted on a rod F, secured in bearings f on the upper part of the frameplate B. The racks c, c', c2, and c3 also respectively interinesh with segmental gears G, G', G2, and G on the rear ends of one of the arms ot' the bell-crank levers g, g', g2, and g3, which hell-crank levers are mounted on sleeves 7L on a rod II, secured in hearings II' on the frame-plate l. On the rod II, adjacent to the ends of the sleeves 71, are also mounted gear or ratchet wheels I, I', 12,13, and It, each containing sixty teeth, or any multiple of tens of teeth desirable.

On the outer ends of the arms lf of the hellcrank levers gy, g', (/2, and ,if are pivoted spri11g-actuated dogs J, J', .Hand di, adapted to engage with the teeth of the wheels I, I', I?, and I: and actuate the same when the rackhars D, D', D?, and D:3 are respectively being raised by the operation of the key-levers on the i'eet thereof, said dogs, however, passing' over the teeth in said wheels freely when said raclebars are returning to their normal positions.

In hearings II on the rear side oli' the frameplate B,nearly opposite the gear-wheels I, I', RIS, and Il, I mount short shafts It., le', le?, and ki", the shaft 'le extending from opposite the left-hand side of the gear-wheel I to opposite the gear-wheel I', and the shaft It' from the gear-wheel I' to the gear-wheel I2, the shaft IOO 7.12 from the gear-wheel l2 to the gear-wheel I8, and the shaft 1.23 from the gear-wheel I3 to the gear-wheel I", as and for the purpose hereinafter set forth. Secured to the left-hand sides of the gear-wheels I, I', I2, and l3 are six carr \v'ing-points Z, equidista nt from each other, one opposite each tenth tooth in said gearwheels,and adjacent to the left-hand sides of said gear-wheels and carrying-points are registering wheels or disks L, L', L2, L3, and L4, each of which is secured to one of said gearwheels and movesin unison therewith. These registering-wheels are also numbered on their peripheries with six series of figures from l to 0, inclusive, each of which series of figures commencing opposite to one of the carryingpoints Z on the gear-wheel adjacent thereto.

On the end of the shaft L', opposite the carrying-points l on the gear-wheel I, is adjustably secured alaterally-projecting arm orlever M, adapted to be engaged-by the carryingpoints l on the gear-wheel I as it rotates the rock-shaft k, and on the opposite end of the shaft k, opposite the gear-wheel I', is a downwardly-pro j ecting lever or arm N, having pivoted thereto a dog n, engaging with the teeth in the gear-wheel I', so that the rocking of the shaft k by the engagement of the carrying-point l on the gear-wheel I moves the lever N, and the dog n pivoted thereto, and engaging with the teeth in the gear-Wheel I', so as to carry the gear-wheel I' forward one tooth. Likewise on the end of the shaft 7a is secu red a like adjustable arm or lever M', adapted to engage with the carrying-points Z on the gearwheel I', and on the opposite end of the said shaft k is secured a like lever N', carrying a dog n', engaging with the teeth on the gearwheel I2, and on the end of the shaft 7a2 alike lever M2, adapted to engage the carryingpoints lon the gear-wheel I2, and on the opposite end of the shaft k2 a like lever N2 and dog n2, engaging with the teeth of the gearwheel I3, and on the end of the shaft 7a3 a like lever M3, adapted to engage the carryingponts Z on the gear-wheel I2, and on'the opposite end of the shaft 7a2 a like lever Y3 and dog n3, engaging with the teeth of the gearwheel I4, each of which series of shafts and the mechanism thereon operate in like manner as does the shaft 7c and levers M and N and dog n connected therewith, first hereinbefore described, and by means of which when the wheel I is moved forward ten teeth the wheel I' is carried forward one tooth, and likewise the carrying forward of the wheel I' ten teeth moves the wheel I2 forward one tooth, and so on throughout the whole series, thus carrying `by tens from the right to the left of said series of registering-Wheels.

On the rear side of the frame-plate B below the shafts 7c k', the., are bearings K', in which bearings are pivoted dogs O, which project forward through openings in the frame-plate B beneath the gear-wheels I, I', I2, and I3, with the teeth of which gear-wheels said dogs are adapted to engage, and in vertical slides o on the hack side of the fram e-plate B below said dogs O are vertically-sliding plates P, P', P2, and P3, one of said plates resting upon each of said groups of key-levers C, C', C2, and C3, so as to be actuated therebyf On the upper edge of each of said plates is also secured an npwardly-projectin lug p, adapted to con tact. with and raise the dog O corresponding therewith into engagement with the gearwheels L or L', the., as the case may be, when the plate having such lug p thereonis raised by the operation of the key-levers of the grou p upon which it rests. Onthe plates P, P', P2, and Pgare also secured wedge-shaped projections q, q', q2, and g3, and on a bar Q, which is secured between the side frames A A at the rear of the frame-plate B and the vertically-sliding plates P, P', P2, and P3', are horizontal bearings or guides R. (See Figs. 7 and 8.) In these guides R are short horizontallysliding` bars R', R2, and R3, said bars being of suflicient4 length to reach from one of the wedges q to another near the inner ends of the bars R'and R3. Iplace pinsrand r' therein, which operate to limit the lateral movelnent of all of said bars, so that if one of the wedges q be raised by movement of one of the plates P it will push all of the bars together and toward the left until the pins r' yr contact with the guides or bearin gs R adjacent thereto, and so long as the wedge q remains in that position none of the other wedges q', q2, or g3 can be raised so as to pass between the ends of the bars adjacent thereto, and in like manner the raising of either of the wedges q', q2, or q2 operates to move the bars R, R2, and R3 laterally, so as to prevent the raising of any of the other wedges. Thus the raising of each wedge operates to lock or prevent the raising of all the others until it is lowered back to its normal position, and as the plate P and wedge q thereon are operated only by the group C of the key-levers, and each of the other plates and wedges described are likewise each operated by a single group of key-levers only, it is manifest that keys in but one group can be depressed at the same time, as the operation of keys in one group operates through the mechanism described to lock for the time such key or keys are depressed the keys in all the other groups.

It will be observed that the outer end of the bar R' and both ends of. the bar R2 and the outer end of the bar R2 have short sections ?"2 hinged thereto in such a manner that as the wedges pass upward they will remain rigid, but will yield as the wedge falls back to its normal position, the object of this construction being to prevent the wedge stick- IOO IIO

ing, a small springr3 operating to return the Y hinged portion r2 back to its normal position when the wedge has been withdrawn.

Across the lower part of the machine, near the-rear edges of the side frames A A, I place a rod S, which operates as a rest for the rear ends S' of the key-levers, and somewhat above the rod S and in the frame at the rear ends S of the key-levers l place a rod 'l`, upon which l mount supplementary levers T', one ot' which is coupled to each of the key-levers representing cents from one to four, inclusive, in the group C, and from ten to forty in the group C, and from one dollar to vfour dollars iu the group C2, and from ten dollars to forty dollars in the group C3, for the purpose of more nearly equalizing the movement or traverse of said hey-levers with the traverse of the remaining key-levers, as hereinafter described. The outer ends of these supplementary levers are coupled each to its respective key-lever at a point t between the axis A of the key-levers and the feet d, d', d2, and d3 of the rack-bars l), D', D?. and D;g at such varying distances as may be required to equalize their movement, the said key-levers to which said supplementary levers '1" are coupled being cut away beneath the feet d, Sac., ot' the rack-bars, so that the feet of the rackbars restupon the supplementary levers '.l", so that when the rear end of the rack-bar is raised the supplementary levers '1"l act upon the foot of the rack-bar to raise it in lieu of the hey-lever itself, as in other cases where the key-lever is not provided with a supplementary lever T', thus allowing a much greater traverse oi' the key-lever than would otherwise he possible, this operation being fully illustrated by the Jfull and dotted lines in Fig. (i. On the key-levers at the rear of the rack-bar feet d, d', d2, and (Z5 are projections U, curving toward the rear faces of said rack-har feet, these projections being of different lengths, as illustrated in Fig. 5, according to the distances of the traverse of thc several key-levers, and are adapted to enter depressions Y in the rear faces of the rackbar feet when raised and lock the rack-bar footin such position until the key-lever is released. rhey also operate to prevent the rack-bar from being thrown up too far by a sudden or sharp blow upon the key-lever. The said curved projection U ou the key-lever also engages with the lower edges of the vertically-sliding plates P, P', P9, and P3, operating the saine, together with the locking mechanism thereon, hereinbefore described.

On each edge of the rack-bars D, D', D?, and D3, below the racks cthereon, are ratchetteeth 1 and 2, in which dogs 3 and el operate, these dogs 3 and t being coupled together by means et' spiral retracting-springs 5, which operate to normally force the dogs and 4 linto contact with the ratchet-teeth 1 and 2. Across the front of the machine in front of dogs 3 and et is a horizontally-moving har G, the ends thereof being pivoted to one of the arms T of the bell-crank levers 8 and t), pivoted to the face of the frame-plate B of the machine, so that the movement of said bellcrank levers operates to move the bar 6 bacl; and forth across the front of the machine. On the har (i are pins 10 and 11, which engage with like pins l2 and 13 in the dogs 3 and 4, by means whereof the movement of the bar t; to the right or left serves to nieve the dogs t3 and -l iu and out of engagement with the teeth l and 2 on the raclt-bais,as hereinafter set forth. entrally on the facesof the rackbars D, D', D?, and D:3 are vertical V-shaped projections 1-i,and ou therearof the rod or bar (lare spring-hooksl, (see detail view, Figa) the vertical projectitms il extending upward on the rack-hais just farenongh so that when the rack-bars are at their lowest point the hooltsl will pass the upper ends thereof, but willengagetherewith when raised above that point.

l`o the arms 1V of the bell-crank levers 8 and El are coupled downwardly-projecting links 17 and 1S, the lower ends of which are pivored to releasing-levers .lil 20, pivoted on the rod A at each side of the machine, the outer ends of which levers being connected together by a cross-bar 'l in Yfront of the keys.

lt will be observed that the dogs il are at all times normally engaged with the teeth 2 on the rack-bars, except during the times the rack-bars are returning to their normal positions. ',lhis is accomplished by depressing the releasing-levers 1i! and 20, which operate the bell-crank levers S and 9, so as to move the horizontal bar l to the right, which operation releases the dogs l- Yfrom the teeth 2 in the rack-bars and at the same time moves the hooks l5 into engagement with the vertical ribs 1T'. on the rack-bars, which prevents the re-engagement of the dogs et with the teeth in the rack-bars until the rack-bars have passed to their lowest point, when the upper ends of the vertical ribs 1t pass be` low said hooks 15, which allows the sliding bar (i to move bacl: toward the left to its normal position, with the dogs t again in engagemeut with the teeth 2 on the rack-bars. The inner ends 22 of the releasing-bars lt) and 2O are also turned downward and pass through openings in the base B', where they engage with the spring-catches 22:3 at the rear end of a cash-drawer 91, mounted in thebase of the case of the machine,and operate to retain the cash-drawer Je in aclosed position until released by depressing the outer ends of said releasing-levers 19 and 20. In the bottom of the case, at the rear end of the cashdrawer Q-l, I also place a retracting-spring 25, which, when the drawer 2l is closed, is compressed and which opera-tes when the drawer is released by the operation of the releasing'- levers 1f) and 2O to throw the drawer 2l open.

To the left-hand side of the frame A A, l secure an alarm-bell 2G and also a pivoted hammer-lever 27, which has aspring-catch 2S, adapted to engage with a pin 29 on the link 17. Vhen the releasing-levers 19 and 20 are depressed, the hammer 31 is drawn back from the bell, and when they are released the retracting-spring 30, secured to the bell-hammer lever 27, causes it to strike the bell 26 and sound an alarm,which is done each time the releasing-levers 19 and 2O are depressed.

1n operation the depressing of any one of IOO IIO

the key-levers in the groups C C C2 C3 thereof raises the rack-bar foot and rack-bar thereon far enough to turn the indicating and registering wheels connected therewith the propel' distance to indica-te and register the amount designated by said key,and at the same time operates the carrying mechanism so as to carry forward by tens, when necessary, so that each amount indicated by the key or keys depressed is indicated on the indicator-Wheels and at the same time added to the aggregate amount previously indicated and registered. The further description of the operation of the other parts of the mechanism having been hereinbefore fully described and set forth in the description thereof, further description is deemed unnecessary; therefore What I claim as new, and desire to secure by Letters Patent of the United States, is-

1. The combination, in a cash indicator and register, of a group of key-levers, some of which are direct and some of which are com-- pound, with a rack-bar foot resting on all of said key-levers, a vertically-moving rack bar secured to said rack-bar foot, and indicatingv and registering wheels geared to and operated by said rack-bar, substantially as and for the purpose set forth.

2. The combination,in a cash indicator and register, of main key-levers and supplementary levers coupled to some of said main keylevers, with rack-bar feet resting upon and adapted to be operated both by the key-levers without supplementary levers and also by the supplementary levers coupled to others of said main key-levers, substantially as and for the purpose set forth.

3. The combination,in a cash indicatorand register, of key-levers, bothsimple and compound, a rack-bar foot resting upon and operated'both by said simple and said compound key-levers, with a vertically-sliding lockingplate adapted to be operated by the rear ends of said levers, and hooked projections on the rear ends of said key-levers adapted to engage depressions in the rear faces of the rack-bar substantially as and for the purposeset forth.

'4. The combination, in a cash indicator and register, of a group of key-levers, a rack-bar foot resting upon all of said group and adapted to be actuated by each lever of said groupindependently of the others7 and registering and indicating Wheels actuated bya rack-bar secured to said rack-bar foot, With a verticallysliding locking-plate resting on the rear ends of all of the key-levers of such group and adapted to be raised thereby, and a dog pivoted to the machine-frame and adapted to be forced into engagement with the teeth of the registering-wheel by said locking-plate when raised by the operation of any of the key-levers, substantiallyas and for the purpose set forth.

5. The combination, in a cash indicator an register, of a series of two or more groups of key-levers and a rack-bar foot, and a vertically-sliding locking-plate resting upon each of said groups of key-levers, with a series of horizontally-sliding bars mounted in bearings on the frame directly above said vertically` sliding locking-plates, and Wedges on said locking-plates adapted to pass upward between the ends of said sliding bars, substantially as and for the purpose set forth.

6. The combination, in a cash indicator and register, of a key-actuated rack-bar, ratchetteeth in the edges of said rack-bar, springactuated dogs operating in the teeth in the edges of said rack-bar, and a vertical rib on the outer surface of said rack-bar, with a horizontally-moving rod having pins thereon engaging with pins on said spring-dogs, and spring-hooks adapted to engage with the rib on the face of said rack-bar, substantially as and for the purpose set. forth.

In testimony whereof I affix my signature in presence of two witnesses.
